A possible race condition vulnerability in drivers/tty/tty_buffers.c
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 2090713]
According to https://www.openwall.com/lists/oss-security/2022/04/21/1 this is actually a concurrency use-after-free in vgem_gem_dumb_create.
Sorry, please ignore that. I'm totally confused.
This was fixed in Fedora with the 5.5.5 stable kenrel updates.
